Abstract
A porous insulating resin tape is fed to an inner or outer surface of one of insulating resin tapes with which a plurality of electrical conductors of a flat cable are coated. Printing is performed on at least one surface of surface of the porous insulating resin tape, soaks into the pores of the porous insulating resin tape. The pores are sealed up when the tape is pressed by a heating/pressing rollers and then baked, and the ink is shut off from outside the pores. The printing can be clearly performed without being discolored.
Claims3
A method for manufacturing a resin-insulated cable, comprising the steps of:
- arranging a plurality of electrical conductors substantially in parallel with one another between two non-porous insulating resin tapes so that said conductors are interposed between said non-porous insulating resin tapes;
- providing a porous insulating resin tape having on at least one surface thereof ink printed characters so that ink penetrates into pores of said porous tape and feeding said porous insulating resin tape to one of an inner surface and outer surface of one of said non-porous insulating resin tapes;
- pressing said non-porous insulating resin tapes and said porous insulating resin tape together by rollers to form a pressed form whereby pores of said porous tape with ink therein are blocked at said at least one surface;
- and
- baking said pressed form so that said porous tape is thinned and ink is sealed therein.
